CRenderHairAccessor rha =3D myHairPrim.GetRenderHairAccessor( 10000, 1000=
);
=85
But I can=92t figure out how to get only the guide hairs=85
Can anyone help clarify how I can access those?
Thanks!

Primitive.Geometry.Points.PositionArray will return you only the points
position for the guide hairs.

Subject: accessing guide hairs control points in C++
Hi,
I=92m doing a custom operator and I need to access the guide hairs contro=
l
points positions. From what I can see from the C++ API, there=92s the
HairPrimitive from whom we can access the CRenderHairAccessor but that=92=
s the
information of all the rendered hairs. I have to loop through every hair
points to make proximity calculations. I just don=92t need to loop throug=
h
every hair, I just want to access the guide hairs to optimize the process=
.
But I can=92t find where to access only those. Can anyone help me figure =
out
how to access that information?
Thanks
